A natural talent who took to the waves at a young age, Bethany won a surfing competition and got sponsored by Rip Curl with her friend Alana Blanchard (Lorraine Nicholson). A bit more into the movie Bethany, Alana, Timmy (Bethany’s brother in the movie) and Alana’s dad, go out to a small secluded beach. They surf for a while then sit on their boards in the calm water talking.
Bethany has her arm swaying in the water while they’re talking and a massive shark comes up from beneath the water taking Bethany’s arm with it. Later in the movie Bethany has to get past many obstacles, like learning how to surf with one arm. She soon gets the hang of it and goes to Phuket after a Tsunami. She helps out and teaches a little boy to surf and shows the other kids that the water is fun. Later on she enters a massive surf comp and competes against Malina (Sonya Balmores) and a few more contestants.
Near the end of the competition, the water is calm but Bethany can feel a wave coming. The wave begins to rise so she paddles out she catches the wave and rides it amazingly. Unfortunately she stood up only a second or two after the finishing horn was sounded making her come 5th in the competition. When they are on the placement stands, Malina her biggest competition takes her up onto the number one stand beside her and shares the trophy with Bethany ,saying that Bethany deserves this because Malina had counted the last wave.
